Abstract
PURPOSE: To construct a deep pit by forming a water stop wall below a row of columns and burying a caission in the ground surrounded by the water stop wall.
CONSTITUTION: A row 3 of columns of soil cement or soil-asphalt cement is constructed in the ground 2 by a boring machine and further a water stop column 8 is constructed just below the row 3 of columns, thus a water stop wall 31 being constructed. Then, a pit is formed by sinking a caission 32 down into the part surrounded by the circular water stop wall 31. The working process is that the caisson 32 with a blade part 33 on the lower peripheral part thereof sinks, digging earth and sand, and while sinking, makes connections. A hole for excavation 35 made under the lower surface of the caisson 32 is provided with iron rods after the caisson 32 being buried at a fixed depth and filled up with concrete. The caisson 32 is provided with lateral holes and caissons 32 thus buried are communicated with a lateral tunnel, thus a telephone cable can be laid.
